「鼻舌身三至謂之為下」者，釋第六、第七句。鼻、舌、身三總皆自地，多分同故；香、味二識唯欲界故；鼻、舌唯取至境界故。於中別者，謂身與觸其地必同，取至境故。「識望」已下，可知。

Regarding the passage from "The three—nose, tongue, and body..." up to "is called lower": This explains the sixth and seventh lines. The three—nose, tongue, and body—are all generally of their own stage, because they are identical for the most part; because the two consciousnesses of odor and taste belong only to the desire realm; and because the nose and tongue only apprehend their objective fields when contiguous. What is specific among them is that the body and the tangible object must be of the same stage, because it apprehends contiguous objective fields. From "Consciousness in relation to..." onward, it can be understood.
